  1. 36. Coining Residual Stresses in Aluminium Ship Structures: Experiments and FE- simulations

    Författare :Rutger Ogeman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The build-up and redistribution of residual stresses obtained by stress coining of aluminium plates containing a hole have been studied experimentally and numerically. The foil strain gauge technique has been employed to measure strains at the bore of a hole during and after the coining process. LÄS MER

  3. 37. Residual Stresses and Strains in Cross-linked Polyethylene Power Cable Insulation

    Författare :Lorant Olasz; Peter Gudmundson; Ulf Stigh; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Other engineering mechanics; Övrig teknisk mekanik;

    Sammanfattning : The subject of this thesis is modeling of the manufacturing process of high voltage power cables with the aim of predicting residual stresses and strains in the cable insulation. The studied material is cross-linked polyethylene (XLPE), which at room temperature is a semi-crystalline viscoelastic solid. LÄS MER

  4. 38. Modelling and simulation of powder pressing with consideration of residual stresses

    Författare :Pär Jonsén; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : In powder metallurgy (PM), production methods are constantly developed and improved to produce component with high precision and strength. Cold uniaxial pressing of powder into a green body is a common process in PM. LÄS MER
